Alternatively, the wireless communication system may also be a next-generation system of the 5G system. Among them, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network, New Generation Radio Access Network). Or, the MTC system.

Wherein, the access device 12 may be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access device 12 may also be an access device (gNB) adopting a centralized and distributed architecture in the 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, radio link layer control protocol (Radio Link Control, RLC) layer, media access control (Media Access Control, MAC) layer protocol stack; A physical (Physical, PHY) layer protocol stack is set in the unit, and the embodiment of the present disclosure does not limit the specific implementation manner of the access device 12 .

A wireless connection may be established between the access device 12 and the UE 11 through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as The wireless air interface is a new air interface; alternatively, the wireless air interface may also be a wireless air interface based on a technical standard of a next-generation mobile communication network based on 5G.

Alternatively, the network management device can also be other core network devices, such as Serving GateWay (SGW), Public Data Network Gateway (Public Data Network GateWay, PGW), policy and charging rule functional unit (Policy and Charging Rules Function, PCRF) or Home Subscriber Server (Home Subscriber Server, HSS), etc. The implementation form of the network management device 13 is not limited in this embodiment of the present disclosure.

As shown in FIG. 2, an embodiment of the present disclosure provides an information processing method, which is executed by a user equipment UE, and the method includes:

S110: Receive indication information; wherein, the indication information indicates whether the UE is allowed to send an on-demand PRS request.

The UE may be a UE capable of receiving a positioning reference signal (Positioning reference signaling, PRS) PRS. For example, the UE may be a UE capable of receiving PRS in an RRC (Radio Resource control, radio resource control) connected state or in an RRC inactive state.

The indication information may come from an access network device, such as a base station, or from a core network device, such as an LMF. It is transparently transmitted from the core network to the UE through the base station, for example, the indication information is transparently transmitted to the UE through the base station from the LMF (location management function) of the core network.

After receiving the indication information, the UE can know that the network side allows the UE to send the on-demand PRS request or prohibits the UE from sending the on-demand PRS request. The on-demand PRS request is a request from the UE to the network side for PRS configuration.

PRS configuration includes but is not limited to one of the indications:

PRS resource configuration; the resource configuration includes but not limited to: time domain resource configuration and/or frequency domain resource configuration;

PRS sending frequency configuration;

The start and end sending time of PRS;

Of course, the above is only an example of PRS configuration, and the specific implementation is not limited to the above examples.

If the network side prohibits (that is, does not allow) the UE to send the on-demand PRS request, the UE may not send the on-demand PRS request to the network device, thereby reducing unnecessary signaling overhead and interference in the wireless environment.

If the network side allows the UE to send an on-demand PRS request, then the UE can send an on-demand PRS (requires PRS) request to the network device according to its own situation to request PRS configuration. For example, the UE has received the PRS configuration pre-configured by the network side, but the UE is for the purpose of saving its own power consumption. If it wants another set of PRS configuration to reduce its high power consumption state, it can request through the on-demand PRS , to request the network device to update the PRS configuration. In this case, the UE can also carry its desired PRS configuration in the on-demand PRS request and inform the network device. In this way, when the network device determines to update the PRS configuration, it will update the PRS configuration for the UE according to the expected PRS configuration of the UE indicated by the on-demand PRS request.

Of course, the above are only examples, and the specific implementation is not limited to the above examples.

In summary, in one embodiment, the method also includes:

When the indication information indicates that the UE is allowed to send the on-demand PRS request, when the UE expects to request PRS configuration or update PRS configuration, send an on-demand PRS request to the network device;

or,

When the indication information indicates that the UE is prohibited (that is, not allowed) from sending the on-demand PRS request, the on-demand PRS request is not sent to the network device. The network device includes but is not limited to LMF, that is, the indication information may indicate that the UE is allowed to send an on-demand PRS request to the LMF, or the UE is prohibited from sending an on-demand PRS request to the LMF.

In one embodiment, the S110 may include:

receiving the indication information sent by the LMF;

or,

The indication information sent by the base station is received.

For example, the LMF sends the indication information to the UE, and the UE will receive the message sent by the LMF transparently transmitted by the base station. Exemplarily, the LMF may send an LPP message to the UE, and the long-term evolution positioning protocol (LTE Positioning Protocol, LPP) message carries the indication information. LTE is an abbreviation for Long Term Evolution (LTE).

For another example, the base station first receives the indication information from the LMF, and then the base station does not transparently transmit it, but sends it to the UE at an appropriate time. Therefore, the UE receives the indication information from the base station. For example, the base station sends to the UE through various broadcast messages. Exemplarily, the UE receives the system message including the indication information sent by the base station. The system message can be a master message block (Master Information Block, MIB) or another system message block (System Information Block, SIB) x, where the value of x can be any positive integer, or it can be a positioning system message.

Therefore, in some embodiments, the S110 may include: receiving a Long Term Evolution Positioning Protocol (LPP) message including the indication information sent by the LMF;

or,

receiving a system message including the indication information sent by the base station.

The LPP message includes but is not limited to: receiving an LPP Provide Assistance data (Provide Assistance data) message sent by the LMF, or receiving an LPP Provide Pre-Defined (Pre-Defined) PRS configuration message sent by the LMF.

In some embodiments, if the LMF has a predefined PRS configuration for the UE, it can be sent to the UE through an LPP message, and the indication information and the predefined PRS configuration can be carried in the same message and sent to the UE. Exemplarily, the LPP message including the predefined PRS configuration includes, but is not limited to: an LPP Provide Assistance Data message or an LPP Provide Pre-Defined (Pre-Defined) PRS Configuration message. When the UE is allowed to send an on-demand PRS request, the on-demand PRS request sent by the UE may include the predefined PRS configuration obtained by the UE.

In one embodiment, the indication information indicates one of the following;

Allowing the UE to send the on-demand PRS request;

or,

The UE is not allowed to send the on-demand PRS request.

In this case, the indication information includes one or more indication bits, and the indication information alone indicates that the UE is prohibited from sending the on-demand PRS request or that the UE is allowed to send the on-demand PRS request.

For example, the indication information may include an indication bit, one of the two bit values "0" and "1" of the indication bit alone indicates that the UE is prohibited from sending the on-demand PRS request, and the other indicates that the UE is allowed to send the on-demand PRS request alone. -demand PRS request. At this time, the UE receives this indication information, and can determine whether the network side allows it to send the UE to send the on-demand PRS request without relying on other information.

Of course, the indication information can use multiple bits in the same field with other information, and different bit values of this field can indicate different contents. In this way, the indication information can share a field with other information, thereby reducing the communication between the network device and the UE. The bit overhead of various information exchanged.

In one embodiment, the indication information indicates one of the following:

When the UE obtains the PRS configuration, allowing the UE to send the on-demand PRS request;

When the UE obtains the PRS configuration, the UE is not allowed to send the on-demand PRS request;

When the UE has not obtained the PRS configuration, allowing the UE to send the on-demand PRS request;

When the UE has not obtained the PRS configuration, the UE is not allowed to send the on-demand PRS request.

The PRS configuration may be a predefined PRS configuration or any pre-acquired PRS configuration other than the predefined PRS configuration.

In another embodiment, the indication information indicates one of the following:

When the UE obtains the predefined PRS configuration, allowing the UE to send the on-demand PRS request;

When the UE obtains the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request;

When the UE has not obtained the predefined PRS configuration, allowing the UE to send the on-demand PRS request;

When the UE has not obtained the predefined PRS configuration, the UE is not allowed to send the on-demand PRS request.

In the embodiment of the present disclosure, the indication information cannot be used alone to determine whether to allow the UE to send the on-demand PRS request. After receiving the indication information, the UE needs to make a comprehensive determination according to whether the network side has delivered the scheduled PRS configuration. For example, the indication information may also be one or more bits, and different bit values have different meanings. Assuming that the indication information occupies one bit, so the indication information has bit values "0" and "1", and the indication information has the same bit value, the indicated result may be different depending on whether the UE has acquired the predefined PRS configuration.

In some embodiments, the LMF may provide an assistance data message through LPP or provide a predefined PRS configuration to the UE through a positioning system message. In some embodiments, the predefined PRS configuration and indication information may be received from the network device in one message, or may be received from the network device through different messages.

The indication information may be: an implicit indication configured by a predefined PRS. In this scenario, if the UE obtains the predefined PRS configuration, it can be considered that the network device allows the UE to send an on-demand PRS request; or, if the UE does not obtain the predefined PRS configuration, it can be considered that the network device does not allow the UE to send an on-demand PRS request. demand PRS request.

For example, the agreement stipulates that UE is allowed to send on-demand PRS request when it receives the predefined PRS configuration, then when UE receives the PRS configuration configured on the network side, it considers itself allowed to send on-demand PRS request to network devices such as LMF , otherwise it considers that it is not allowed to send on-demand PRS requests to the LMF.

As shown in FIG. 3 , an embodiment of the present disclosure provides an information processing method, which is executed by a UE, and the method includes:

S210: Receive area information, where the area information indicates a valid area range.

The effective area range is: the effective geographical range of the indication information indicating whether the UE is allowed to send the on-demand PRS request.

In some embodiments, the indication information may be received by the UE from a network device, for example, from an LMF or from a base station.

In some other embodiments, the indication information may be stipulated in a protocol, so that the UE may obtain the indication information from a protocol file.

After receiving the area information, the UE needs to determine whether it is within the effective area indicated by the area information. Only within the corresponding effective area will it determine whether the network device allows itself to send an on-demand PRS request according to the indication information.

When the UE moves out of the effective area indicated by the area information, it no longer determines whether it is allowed to send the on-demand PRS request according to the indication information. If the area information comes from a network device, the area information and the indication information can be carried in the same message, or can be carried in different messages and sent to the UE. In this way, the UE may receive the indication information and the area information in one message at the same time, or may receive the indication information and the area information in different messages respectively.

For example, the area information may also be carried in an LPP message from the LMF or a system message from the base station. If the UE receives the indication information and the area message in one message, the UE will know whether it is allowed to send on-demand PRS requests within the scope of the corresponding area through a message.

Exemplarily, the receiving area information includes: receiving an LPP message containing the area information sent by the LMF; the LPP message includes but not limited to: an LPP providing assistance data message or providing a predefined PRS configuration message;

Or, receive a system message including the area information sent by the base station.

The indication information and the area information may come from the same network device, for example, from the LMF or the base station at the same time.

The area information includes one of the following:

Cell ID;

sending and receiving point ID;

System message SI area ID;

Access network notification area (Radio access network Notification Area, RNA) ID.

One or more cell IDs are included in one piece of area information, and the cell indicated by the cell ID included in the area information is the effective area range of the indication information.

One or more TRP (Transmission Reception Point, TRP) IDs can be included in one area information. The coverage of the TPR indicated by the TRP ID included in the area information is: the effective area range of the indication information.

The system message area ID is the effective area of some cross-cell or block base station system information. If the area indicated by the system message area ID included in the area information is the effective area range of the indication information.

The RNA indicated by the RNA ID may be an area for paging RRC inactive UEs. In the embodiment of the present disclosure, the RAN indicated by the RNA ID included in the area information is the effective range of the indication information.

In this way, by receiving the validation information, the valid geographical range of the indication information can also be known.

If the effective area range of one indication information is larger than one cell, it realizes that one indication information takes effect in multiple cells, and reduces the phenomenon of large signaling overhead caused by issuing indication information one by one.

In some embodiments, the effective area range of the indication information may be pre-agreed, for example, pre-agreed in an agreement. At this time, after receiving the indication information, the UE determines the effective area range of the indication information according to the pre-agreement, and does not receive area information from the network device any more.

Exemplarily, the protocol stipulates that an RNA or a tracking area (Tracking Area, TA) or the like may be used as the effective scope of the indication information.

The method also includes:

When it is determined according to the area information that the UE is located within the effective area of the indication information, determine whether to allow the UE to send an on-demand positioning reference signal PRS request according to the indication information.

As shown in FIG. 4, an embodiment of the present disclosure provides an information processing method, which is executed by the LMF, and the method includes:

S310: Send indication information, where the indication information indicates whether the UE is allowed to send an on-demand PRS request.

The LMF may send the indication information to the UE or the base station. For example, the LMF directly sends the indication information to the UE through the LPP message. For another example, the LMF sends the indication information to the base station, and then the base station sends the indication information to the UE.

Exemplarily, the S310 may include:

sending an LPP message including the indication information to the UE;

or,

Sending an NRPPa message including the indication information to the base station, where the indication information is used to be sent by the base station to the UE.

The LPP message includes, but is not limited to, an LPP Provide Assistance data (Provide Assistance data) message, or a Pre-Defined (Pre-Defined) PRS configuration message.

The NRPPa message includes but is not limited to: an NRPPa location information request message, and the NRPPa location information request message may also be used to instruct the base station to provide the LMF with the PRS configuration for the UE. In this way, the exchange of various information between the base station and the LMF is completed through one NRPPa message, which reduces the number of information exchanges and improves the interaction efficiency. It can also be an NRPPa PDU. When the LMF needs to send new or updated positioning assistance information to the base station, it sends the indication information through the NRPPa PDU. Exemplarily, the NRPPa message may include: the LMF requests TRP information (TRP information request) information from the base station. The NRPPa message may carry the indication information and send it to the base station.
